Question

They talk of the price of oil by the barrel, how many gallons of oil is in one of these barrels?

Answer 1

The barrel of petroleum, 1866 – present, a unit of capacity = 42 U. S. gallons (or about 5.61458 cubic feet, and though approximately 158.987 liters taken as = 159 liters, by, for example, the U.S. Census Bureau Harmonized System), measured at a temperature of 60° Fahrenheit.1 It is a unit of account; actual barrels containing 42 gallons of crude oil have not been used for more than a century, if ever.

Answer 2

One barrel = 42 US gallons = 5.615 cubic feet.

However, people must be careful no confuse crude oil with gasoline.  The number of gallons of gasoline that can be obtained from each gallon of crude oil depends on the quality of the base crude and the refining method, and is generally less than 1.00
